About Duwell

Our Experience

We moved to Waiuku 14 years ago to a wonderful property that for many years been used for intensive dairy farming. I very quickly found out the downside of the pasture here. It had been drenched in Superphosates for over 50 years. Without realizing we had bought acres of “Disaster Pasture!!” The grass affected our horses very badly making them difficult to work with and ride. They would rip around the paddock and screech up to the fences only just stopping at the last minute. Some horses developed full blown staggers and others more subtle subclinical staggers issues like excessive spookiness, nervousness, agitation and reactive unpredictable behaviour like sudden bucking episodes and girthyness. One lovely little mare I had when ridden would spook 20 feet in one direction and in the next millisecond spook 20 feet the other way, walking or trotting across a grass paddock. She would also duck when birds flew above her head or when we went underneath power lines that were nowhere near her. At the same time she would have “no go” and was over all very hard work to ride but I knew this wasn’t her true nature.

I was determined to find the reason for these issues. As the organizer of horsemanship clinics around my area I got to see many other distressed owners with horses that were affected with the same grass issues. We began to trial different products and could see the difference they made to the well-being of the horses. Previously spooky and nervous horses became calm and settled.

About Duwell

Our Knowledge Base

At our property I have run extensive long duration case studies with horses with challenging health and behaviour issues and have painstakingly research exactly the right ingredients to solve these issues. This was a very costly process but a highly effective way to test our products and we gained huge amount of hands on knowledge which cannot have a price put on it. We recorded these case studies and have them as a knowledge base on our website so other owners facing the same distressing problems know there is light at the end of the tunnel.

Case Studies

One recent case study is Tigger, a horse that through change in living circumstances was near death before being rescued by us. Tigger is now back to full health and has been adopted by a wonderful caring lady that loves him to bits and Tigger enjoys a relaxing life as a paddock horse.


Why I Love Helping Others

I am so pleased to share my knowledge with you so together we can ensure your horses are happy healthy and calm. There is an absence of correct information and actual hands on advice from people that have solved these extensive grass and feed issues that are widely experienced by horse owners in New Zealand in New Zealand.

How Else Do We Give Back?

I have taken on many rescue horses, bought them back to health then have found them wonderful loving homes. This is not a cheap thing to do but so worth it! We also provide event sponsorship, sponsor riders and proudly support Ambury Park Centre for Riding Therapy.


Tigger when he first arrived.
He was a very sick boy.


Tigger 8 weeks later.
Still a way to go but looking so much better.

As I developed and tested products, talking with customers, I realized that there was a lot of misinformation out there around horse nutrition and also a complete lack of practical advice for people when things went wrong. I wanted to change that.

I wanted to develop effective and affordable products that would enable horses to be healthy, be trainable and rideable. DUWELL products aim to:
